Determination of boron in organic compounds by microwave plasma–atomic emission spectrometry

Abstract

We propose a method for the determination of boron in aliphatic and aromatic trifluoroborates (including perfluorinated ones), ethers, and organoboron compounds containing dioxoborolane fragments, pyridine, and pyrazole rings, and triple bonds. The substances were decomposed by the oxygen flask combustion method. Boron was determined on an Agilent 4100 microwave plasma–atomic emission spectrometer. A number of organic compounds were analyzed, and the mass fraction of boron was determined with an error less than ±0.3 abs. %.
